The potentiometric form of this process involves measuring the potential difference between two cells and using the Nernst Equation. When this process is done using a polyprotic solution, there will be more than one equivalence point. At the half equivalence point of this process for a buffer solution, the pH equals the pKa
The potentiometric form of this process involves measuring the potential difference between two cells and using the Nernst Equation. When this process is done using a polyprotic solution, there will be more than one equivalence point. At the half equivalence point of this process for a buffer solution, the pH equals the pKa, as shown by the Henderson-Hasselbalch Equation. For 10 points, name this process that often makes use of indicators such as phenolphthalein (FEE-nul-THAY-leen) and a buret.
